unable to SSH to SSR

No ability to ssh to SSR

SSH is not available by default by design with Mist. If you would like to have remote shell access (no config options, no OS access) or you would like to have Extra CLI (drop SSR config statements), you would need to talk to your Sales Engineer (SE) and ask them to enable it for you. They can also file a Feature Enhancement Request (FER) for you if you would like to see SSH access enabled by default in the future.

For Conductor managed SSR, please see the following documentation:
